Reduce Scope II Emissions: Scope II emissions are indirect Green House Gas (GHG) emissions associated with the purchase of electricity, steam, heat, or cooling.
Reduce energy costs: Currently, the cost of cleaner form of energy especially wind and solar power is lower than the cost of conventional form of energy. Adopting cleaner of energy thereby can help reduce the cost of energy.
Improve Customer Appeal: A recent report commissioned by World Wide Fund for nature (WWF) revealed that Consumers are changing their behaviour, with searches for sustainable goods increasing globally by 71% since 2016. In India, there is a 190% increase in engagement and awareness about the devastating impact of the loss of nature. In a 2019 online survey, 50% of respondents worldwide said they switched products or services because a company violated their values related to nature. Adopting cleaner form of energy, thereby, help promote customer appeal of the business.
Cater to Regulatory Requirements: C&I can claim the green power against regulatory requirements such as Renewable Purchase Obligations (RPOs) as imposed by local DISCOMs for open access / captive power purchase.
Considering C&I establishment contributes to half of India’s power consumption, adopting cleaner form of energy by C&I can help meet India its clean energy targets.

Technical FAQs

The definition of Open Access in the Electricity Act, 2003, is “the non-discriminatory provision for the use of transmission lines or distribution system or associated facilities with such lines or system by any licensee or consumer or a person engaged in generation in accordance with the regulations specified by the Appropriate Commission”.
According to sub-section 2, of section 42 of the Electricity Act 2003, electricity consumers now have the right to procure power from the supplier of their choice other than the distribution company that they were buying from. They can use the existing transmission and distribution infrastructure after paying appropriate charges determined by their respective State Electricity Regulatory Commissions (SERCs)

We need to first understand what PPAs are before moving to vPPAs.

PPA- Power Purchase Agreement

A power purchase agreement (PPA) refers to electricity supply agreement between a power producer and power buyer. The PPA refers to all of the commercial terms for the sale of electricity, including when the project will begin commercial operation, schedule for delivery of electricity, penalties for under delivery, payment terms, and termination.

vPPA- Virtual Power Purchase Agreement

A Virtual Power Purchase Agreement (vPPA), also known as a Synthetic PPA, is a popular type of renewable energy contracting structure that provides a financial hedge against future energy fluctuations. With a virtual PPA, the energy doesn't physically flow from the project to the buyer. It is merely a financial contract, which is why it's often referred to as a "financial PPA". In a vPPA, the energy is sold on the wholesale electricity market and the vPPA buyer will get RECs by paying a difference between vPPA price and wholesale market price (in some cases, the buyer may also receive the money back from the generator in case the wholesale market price is higher than the vPPA price). The buyer continues to get their electricity from their utility company at their utility's rate.


vPPA, being a financial contract, does not affect the traditional electricity supply for an organization directly. The organization continues to purchase electricity from the utility, in addition, enters the vPPA for RECs to meet its clean energy obligations.
Organizations exploring the vPPA structure are typically focused on sustainable business practices, reducing carbon footprint, and investing in renewable energy. Just as with any investment, the impact of these “green” initiatives is important in evaluating their true return of investment. For example, purchasing unbundled RECs is a low impact solution for achieving renewable energy goals. These RECs are easily attainable, may come from new or existing resources anywhere in the county, from any “renewable” energy resource.
Unlike a traditional Unbundled REC purchase, which always costs money, the vPPA swap provides RECs at a price determined by the net difference between the fixed vPPA Price and the wholesale market price. A positive difference between the market price and the fixed vPPA price can lead to significant positive cash flows while ensuring issuance of RECs.
By entering a long term Synthetic PPA, the buyer is locking in a price for Bundled RECs based on the wholesale market price of electricity. If wholesale electricity prices rise, then the buyer’s conventional energy supply costs is also expected to rise. The buyer in that scenario, may make money on the vPPA deal which can offset the higher energy costs. Conversely, if the VPPA price is greater than the wholesale market price, the buyer will be paying the net difference to the project to provide their required fixed revenue stream.

An I-REC (International Renewable Energy Certificate) is a type of Energy Attribute Certificate (EAC), which represents one megawatt hour (MWh) of electricity produced by renewable sources. Organizations exploring the vPPA structure are typically focused on sustainable business practices, reducing carbon footprint, and investing in renewable energy. Just as with any investment, the impact of these “green” initiatives is important in evaluating their true return of investment. For example, purchasing unbundled RECs is a low impact solution for achieving renewable energy goals. These RECs are easily attainable, may come from new or existing resources anywhere in the county, from any “renewable” energy resource. Unlike a traditional Unbundled REC purchase, which always costs money, the vPPA swap provides RECs at a price determined by the net difference between the fixed vPPA Price and the wholesale market price. A positive difference between the market price and the fixed vPPA price can lead to significant positive cash flows while ensuring issuance of RECs. By entering a long term Synthetic PPA, the buyer is locking in a price for Bundled RECs based on the wholesale market price of electricity. If wholesale electricity prices rise, then the buyer’s conventional energy supply costs is also expected to rise. The buyer in that scenario, may make money on the vPPA deal which can offset the higher energy costs. Conversely, if the VPPA price is greater than the wholesale market price, the buyer will be paying the net difference to the project to provide their required fixed revenue stream.

Like all EACs, I-RECs enable companies to credibly demonstrate renewable energy consumption and report lower Scope 2 emissions. I-RECs are particularly useful to companies with global operations and a target to source 100%. As corporate renewable energy procurement and reporting on energy use and emissions faces increasing scrutiny, procuring bundled RECs will be the best practice for meeting corporate renewable energy goals.

The I-REC Standard operates a single global registry through which energy products from renewable sources can be certified through the electricity supply chain. Established in 2014, it provides an electricity attribute tracking system that can be introduced to any country. It is a non-profit foundation based in the Netherlands with the goal of empowering electricity purchasers with the ability to make renewable consumption choices in any region of the world. The I-REC Standard is acknowledged by major reporting frameworks such as the Greenhouse Gas Protocol (GHGP) and Carbon Disclosure Project (CDP) as a reliable backbone for credible and auditable tracking instruments. It ensures the highest quality systems and adherence to best practices designed to avoid double counting, double certificate issuance, and double attribute claims.
